TP, Smitty....I'll reply, because I think that getting Gay is a good idea.
I'd do your trade ,although, I'd rather wait till Jan 15 and use Zeller so Amir's larger salary could be used in another trade.
I'd love to roll out a lineup of Horford, Gay, Crowder, Bradley and IT.
Gay is still relatively young (only 30), durable and gives us rebounding and scoring at the wing. 35% career 3 point shooter averaging 6 rebounds per game on a team that has a monster rebounder and averaging 19 ppg is someone we could use.
And I agree. Unless injured (and he has proven his durability) will opt out. No brainer for me.
Also, I never bought into that specious negativity on him that every team that he's left gets dramatically better (implying that is because he left.)
